because of the really low pressure
in the tornado. They figured that the
higher pressure in the house would knock down the walls trying to get
out. So they said you should open your windows to equalize the
pressure. It turns out that more damage can be done by opening the
Some people thought that tornadoes couldn't cross mountains or rivers.
This is true for small tornadoes, but the strong ones--the ones which
cause the most destruction--can cross almost anything.
